Sodium oxalate has a molar mass of $134 \frac{g}{m o l}$ $134 g/(mol)$

$Let us use this equation to answer the question:$ $color(magenta)"Let us use this equation to answer the question:"$

atomic weight of element $\times$ $xx$ number of atoms given by subscript $=$ $=$ molar mass

Based on the chemical formula, we have 2 sodium atoms. The atomic mass would have to be multiplied by 2 to obtain a mass of 45.98g/mol

Next, you have 2 carbon atoms, so you would multiply the atomic mass of C by 2 to obtain a mass of 24.02 g/mol

Finally, since there are 4 atoms of oxygen, the atomic mass of O has to be multiplied by 4 to get a value of 64.00 g/mol.

Now you want to add the mass of each atom together to obtain the molar mass of the entire compound:

$45.98 g/mol + 24.02 g/mol + 64.00 g/mol = 134 g/mol$ $color(blue) ("45.98 g/mol + 24.02 g/mol + 64.00 g/mol = 134 g/mol")$
